Making Stray Light Analysis

The following procedure helps you set up a Stray Light Analysis.

To make a Stray Light Analysis:

  1. Create an Irradiance, a Radiance or an Intensity sensor.
  2. In the General section, in Layers, select Sequences
  3. Define the Maximum number of sequences to calculate.
  4. Define the sequences per Geometries or Faces.
  5. If you created an Irradiance sensor, Sort the sequence per Relative energy or Peak value.
    In the Sequence Detection tool the sequences will then be ordered either by decreasing energy or by decreasing peak value.
  6. Create a Direct or Inverse simulation.
  7. For the Inverse simulation, in the Simulation Options, activate the Monte Carlo algorithm, the Dispersion, and deactivate the Splitting.
  8. In the General section, set the Light Expert to True.
    Note: Whether Light Expert is activated or not during the simulation definition, it is automatically used as a background process as soon as data are separated by sequence. The advantage of activating Light Expert manually is that it allows you to activate the option only for the sensors you want to analyze and to determine the number of rays you want to embed in the results.
  9. In the 3D view, click Compute to launch the simulation.

    At the end of the simulation, under the Simulation node, two files are generated:

    • a XMP map including layers displaying the contribution of each sequence.
    • a .lpf file.
